With that many people converging on a normally empty field, Bowman has to plan for every contingency.
Bowman said they have a specific security plan "for this event, at this location, this year."
In planning the event they've been in touch with all levels of law enforcement, from the local sheriff to the State Police and the Department of Homeland Security.
Interspersed throughout the crowd are people that Bowman described as WMD inspectors. They're dressed in plain clothes and don't have the authority to make arrests. But they're trained to look for packages, and anything else that looks suspicious, and are in constant contact with law enforcement.
All concertgoers are subject to hand search and search by metal detectors.
The event staff is divided into 18 different categories, from stage, video and pyrotechnics, to catering crews, ushers and security.
Potential weather emergencies -- including thunderstorms, hale and tornadoes -- are divided into 10 categories.
For each weather event, every category of crewmember has a different assigned duty or meeting place. The result is a massive 10-by-18 rubric of safety.
"This is a very safe event," Bowman said, in a bit of understatement.
And the planning doesn't stop when the concert starts.
Rock stars have a reputation as reliably unreliable, so Bowman has to be ready with on-the-fly adjustments.
"We're always getting changes on the artist level," he said. "I'm always anticipating the next element that needs to happen to put on a seamless show."
That means Bowman, an Aerosmith fan, won't really be able to get into the spirit of the concert.
"I grew up in the '70s and '80s. I had a 45 of 'Walk this Way,'" he said.
But asked if he would be able to relax and enjoy one of the bands of his childhood, Bowman had a one-word answer: "No."
